This invention relates to sonnd-deadening musings for typcwritingmachines, in Wlnch the machine con'ipletely enclosed. Within tbe t except for the keyboard, which preti-ados through the front Wall toftheoutside thereof.

Acoordinato this invention; the typewriter is placed in au casing comprising a bodyLpiirt and alcover thereforl The bodyl an integral partof rear, side andf'ront Walls,

tlie latter being provided with an opening tin-(nigh which the keyboard oli` the machine entends to the exterior, torender the inacliiiie operable without displacing the cover, which, when inits effective or closeil; posi` tion,` completely prevents the emission clV sounds and confines tliein Within tlie Casing.

'llo this end, there is" prov-ideil1 a cord wound aroandthe periphery oi" a dro-m*operatively connected to a lever ami-infront oit the casing; Ono end of the cordis fastened to the carriagdrelese"lever of tliefmaehinein a manner toafordthe re` leasing ofthe carriago` when the dramas rotated to pull the `earriagge "in letterspace direction. The other* end of the cord is se`- cured to the frame of tliefoarriageand1 is ledl toy tliedrnm by means of cooperating pulleys. Since" the carriageii's` at" all posi-A tions 'releaocilto movein Co'unter-letteI-LSpace direction, the drum may be rotated topl'lll on tlietcarriage directly in` returningldirec tion. Ally-.releasing the? lever arm `in front ofthe casingptlie carriage-release lever' `is automatically restored to its normal posi tion; tlieroliyiholding the carriageiin place ready :for typing.
